Subject: [PATCH 09/25] iwlwifi: mvm: replace the number of blocks calculation
Date: Tue, 24 Jan 2017 00:03:34 +0200	[thread overview]
Message-ID: <20170123220350.25305-10-luca@coelho.fi> (raw)
In-Reply-To: <20170123220350.25305-1-luca@coelho.fi>

From: Sara Sharon <sara.sharon@intel.com>

The logic in the paging calculations is a bit hard to
follow. Replace it with a kernel define.
